VPC Peering on different region in AWS

Introduction:

A VPC peering, a networking connection between two VPCs that enables to route traffic applying private IPv4 addresses or IPv6 addresses. This tutorial will cover creating VPC Peering on AWS.

Procedures:

I have shown in previous videos how to create VPC, EC2 instances, and Launch instances in different Regions. If you have any doubts about it please watch those videos for better clarification EC2 instance Creation: https://www.youtube.com/watch?v=s9traU-3fQI&t=15s VPC creation: https://www.youtube.com/watch?v=tffhGE48e4o&t=115s Launch EC2 instances in different Regions: Here I have already created VPC and launch Instances. Now I will launch the Instances in the different regions for making the peering connection Now I will launch Mumbai region Instance

snap1 Now I will launch the North Virginia Instance snap2 Now I will switch users and try to ping those instance IPs to each other but I didn’t get connections to each other. snap3 snap4 Now I will show how to create a peering connection to different region instances. For that go to peering connection and click peering connection and enter into the create peering connection snap5 Inside the peering connection enter the peering connection name and enter the source VPC to the source test box snap6 Now you have to do the acceptor tab. Here I am using a different region VPC so I have entered here another region VPC. For that, I need to go to that region (North Virginia) and enter the VPC window snap7 snap8 Then back the peering connection window and change the region to another region copy the VPC id then paste it to the acceptor text box then click create peering connection snap9 You cannot accept the peering request from the source you can only accept the request to the destination region. For that go to that region and click the peering connection and you can see the requesting acceptance select that and click action and accept a request snap10 Now the peering connection is active. Now, will add the rules for the peering connection to the routing table on both regions. For that go to VPC and click route table and edit routes add the peering connection to there snap11 snap12

Now you will check the instances that are pinging each other snap13 snap14 With this method, VPC Peering on a different region in AWS is comes to an end.
